Okay as you can see there are several viable ways a small critter like a ratty could get into the drain. There is a vent, usually slightly above the
foundation on the exterior of the house...over time this vent can rot inside and the valve can become stuck open allowing access to intruder critters.
It's a bit of a drop...usually about 4 to 6 feet and it's likely slick with mildew and whatnot, making it impossible for a critter to get out.
There is also another valve under the cement that often becomes stuck open.
Chances are it was a little ratty who either came in from the main sewage line during wet weather (the water levels rise and rats are great swimmers)
or fell in from ground level.
More likely it was not drinking the water but trying to breath. The effect of gravity with the push of air and water makes the pipes a bit shallow
airwise and it was likely having a hard time breathing.
The little critter more than likely had been holed up in one of the redundant pipes (the basins) used for overflow and to limit backups. And when the
water started running it started getting hard to breath...so it would naturally go towards the flow of air...even though it meant getting wet and
Not to worry though. Ratty likely died in the pipes and his little decomposed corpse would be (hopefully) washed away with the sewage water.
side note...rats will lose their fur quite dramatically if under severe stress...like being in a drain. My bet is a rat got in but couldn't get out
and was just gasping for air at the drain cover.
Poor ratty. You might wanna snake the drain BTW...make sure the ratty corpse isn't clogging things up, and to make sure your backwater valve isn't
stuck open allowing for any other critter to make it into the sub plumbing of your house. Also check the plumbing vent on the outside...make sure the
cover is intact or the drain screen is on. You can snake that one too to make sure the valve isn't blocked.
